1Z0-997-26 Multicloud And Hybrid Practice Question
When designing a high-performance hybrid architecture integrating an on-premises data center with OCI, which THREE key factors should be evaluated to optimize network throughput and reliability?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
BGP timer tuning for faster convergence and failover detection
When planning FastConnect or VPN connections, factors such as MTU size (Jumbo frames), redundant physical links or diverse paths, and BGP multipath or dead-peer detection timers heavily impact performance and reliability.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
BGP timer tuning for faster convergence and failover detection
Why this is correct
Tuning BGP keepalive and holddown timers allows faster detection of link failures.
- ✓
Maximum Transmission Unit (MTU) size configuration (supporting Jumbo Frames up to 9000 bytes)
Why this is correct
Configuring larger MTU sizes improves throughput for large data transfers in hybrid setups.
- ✗
Enabling public IP addresses on all internal database nodes
Why it's wrong here
Database nodes in a secure hybrid architecture should remain on private subnets.
- ✗
Configuring Local Peering Gateways for on-premises connectivity
Why it's wrong here
Local Peering Gateways connect OCI VCNs, not on-premises data centers.
- ✓
Physical path diversity and carrier redundancy for FastConnect circuits
Why this is correct
Ensuring diverse physical routing paths prevents single points of failure in hybrid connectivity.
